Abstract

Dynamic analysis of particulate emissions from vehicles has been a challenge. A dynamic particulate measurement method applying light scattering theory is being developed at Victoria University. A particle model has to be set to apply light scattering theory. To simplify the problem, a Fraunhofer diffraction model has been used. The scattered light intensities have been measured at different scattered angles from the particles in an exhaust stream with a lock-in amplifier system, and then the scattered light intensities were used in the model to solve the particle size distributions. Since the model equations are non-linear, analytical solutions cannot be obtained easily. (Author/publisher) For the covering entry of this conference, please see ITRD abstract no. E210413.
